Tadpoles hatch from eggs laid in the water. They look like tiny fish. Over the course of their development, which can take one to three years, they increasingly resemble adult bullfrogs. A tadpole's head begins to change, its legs begin to sprout and its tail is absorbed into its body. It also loses its gills and begins to use lungs to breathe. Its digestive system evolves to handle an adult bullfrog diet, which includes insects, worms, snakes and fish.
